1. A processing system for an input device, the processing system comprising:

  • a transmitter module comprising transmitter circuitry, the transmitter module coupled to a plurality of transmitter electrodes and configured to drive a first end of a first transmitter electrode of the plurality of transmitter electrodes to produce a first voltage gradient across the first transmitter electrode;

    a receiver module, the receiver module configured to receive a plurality of resulting signals with a plurality of receiver electrodes, the plurality of resulting signals each comprising effects of the first voltage gradient; and

    a determination module configured to determine a two-dimensional capacitive image based on the plurality of resulting signals, and wherein the determination module is further configured to determine positional information for a first input object located within a sensing region based on the capacitive image.
